She said that, in the early hours of the morning, she could hear a man talking downstairs, so she went onto the landing to have a peek. When she looked downstairs, she could see her mum and her uncle in the kitchen. Her mum was sitting on the kitchen unit and her uncle was leaning against it. Then they started kissing, or "snogging each other's faces off", as my niece put it.

I don't want to believe it, but I really don't think that my niece would lie about something like this. From the details that she told me in her story (the way her mum was sitting etc.), it doesn't sound as though it's something that she'd just make up. She said that she wants to tell her mum that she saw them, but she's too scared. She has asked me if I'd speak to her instead.

I'm pretty close to my sister, but I don't know how I'd go about bringing this up! Should I just leave it, or shall I do as my niece has asked?

This is a tricky one. I think that you need to speak to your niece again before you chat to your sister (if you intend to). If it turns out that your sister is having an affair, would your niece be able to deal with that and the consequences that it may bring? Does your niece even think that they're having an affair? A 12-year-old may not have thought about the situation in the way that you have. She may just simply want to tell her mum that she saw them and maybe hasn't thought about the fact that they could be having an affair? Sorry, my answer probably sounds stupid, but I don't know how best to explain what I mean!

i agree with Tegan id go and reaffirm beyond and reasonable doubt that she definitely saw what she saw and didnt mistake something else for that. After all if you did take this to your sister it could quite happily split up the family

I agree with what has already been said. However, if your sister is having an full-blown affair with him, I think the truth needs to come out. Some people may say "Oh, it'll just break up their family; it's none of your business!", but, if they are having an affair, I think they've already done that themselves.
